What are the main blocking points when deploying PLC in a building?
(Please refer to the document on LEA’s website entitled: “Constraints when deploying PLC equipment using private internal electrical networks”) A26 : The electricity supply to a building is divided into sectors for safety reasons. The classic structure is generally as follows: • A low voltage main distribution board, which is the entry point for the three phase public electricity supply, supplies a secondary distribution board on each floor, for example, (generally supplied in three phase from the main distribution board), which includes the protection elements in the form of differential circuit breakers. The secondary distribution board then supplies single phase electricity to the zone that it serves. • The end/final distribution board: sometimes used to distribute the supply room by room, for example. From an end/final distribution board you can have the potential for 3 separate sub-networks from one three-phase electricity supply. This division of the electrical supply network is
